Device for mounting railroad tracks on a substructure

Abstract

The invention relates to a device for mounting rail-road tracks ( 22 ) on a substructure ( 20; 20 a, 20 b ), comprising two angle guide elements ( 30; 30 a, 30 b ) disposed on both sides of the rail foot ( 22 a ) for each mounting point, and one support element ( 28 ) on the side facing away from the rail foot ( 22 a ) of each angle guide element ( 30, 30 a, 30 b ), and a support unit ( 26 ) disposed beneath the angle guide element ( 30; 30 a, 30 b ) and support elements ( 28 ) of the mounting point and comprising two threaded bolts ( 42 ) for tightening rail clamps ( 32 ), disposed such that they extend through openings in the angle guide plates ( 30; 30 a, 30 b ) in the installed state.

The invention claimed is: 
     
       1. A device for mounting railroad tracks on a substructure, each mounting point comprising:
 two angle guide elements which are disposed respectively on either side of a rail foot; 
 a respective support element on a side of each angle guide element facing away from the rail foot; 
 two threaded bolts for tightening tensioning clamps which are arranged such that in an installed state they extend through openings in the angle guide elements; 
 a support unit which is disposed beneath the angle guide elements and the support elements of the mounting point; and 
 a spacer plate between a respective one of the angle guide elements and the support element adjacent to the respective angle guide element. 
 
     
     
       2. The device according to  claim 1 , wherein
 the tensioning clamps are each substantially W-shaped, to form a respective central loop which partially surrounds a respective shaft of the threaded bolt and rests against the angle guide element. 
 
     
     
       3. The device according to  claim 1 , further comprising two sleeper screws or bolt connections which respectively pass through one of the support elements and through a through-hole in the support unit. 
     
     
       4. The device according to  claim 1 , wherein
 the support elements have a mounting contour, which interacts with a complementarily formed attachment contour of the support unit in order to attach the support elements to the support unit in a pre-assembly position. 
 
     
     
       5. The device according to  claim 4 , wherein
 the mounting contour is a clip mechanism. 
 
     
     
       6. The device according to  claim 1 , wherein the threaded bolts are securely connected to the support unit. 
     
     
       7. The device according to  claim 6 , wherein
 the threaded bolts are welded to the support unit. 
 
     
     
       8. The device according to  claim 1 , wherein
 the threaded bolts are countersink screws inserted into the support unit from the side facing away from the angle guide elements in the installed position. 
 
     
     
       9. The device according to  claim 8 , wherein
 the threaded bolts are assembled with the support unit to form one unit. 
 
     
     
       10. The device according to  claim 1 , further comprising at least one elastic intermediate layer arranged between the angle guide elements and configured to bear the rail. 
     
     
       11. A railroad sleeper configured for use in a turnout area comprising the device for mounting railroad tracks according to  claim 1 . 
     
     
       12. A fixed track for a section of railroad comprising carriers having at least one device for mounting railroad tracks according to  claim 1 . 
     
     
       13. A device for mounting railroad tracks on a substructure, each mounting point comprising:
 two angle guide elements which are disposed respectively on either side of a rail foot; 
 a respective support element on a side of each angle guide element facing away from the rail foot; 
 two threaded bolts for tightening tensioning clamps which are arranged such that in an installed state they extend through openings in the angle guide elements; 
 a support unit which is disposed beneath the angle guide elements and the support elements of the mounting point; and 
 projections on the support unit which in the installed state extend upwards and have locating surfaces configured to rest against counter surfaces of the support elements on the respective sides of the support elements facing towards the angle guide element.
